Application filed July 14, 1921. Serial No. 484,723.

To all whom it may concern.

Be it known that I, ROBERT BLANK, a citizen of the United States of America, residing at Columbus, in the county of Franklin and State of .Ohio, have invented certain new and useful Improvements in Fireproof Waste Guns, of which the following is aspecification. f 1

My presentinvention relates to receptacles, and particularly to the arrangement of'a closure or closures and a mechanism for automatically actuatingthe same. The invention may be used in connection with various receptacles where it is desiredto'prevent the escapeof odors, to exclude vermin or to prevent communication of fire.

-I show the invention as embodied in a waste-collecting can which includes a body and a removable cover. The cover is provided with diametrically opposed door openings and with inward swinging doors for closing such openings. The door actuating mechanism is housed within the cover between the doors and' comprises a, yielding linkage connected with the doors and operating to urge both doors closed at all times,

while permitting either door or both to be pushed open against moderate resistance. In this preferred form, the closing mechanism is so contrived as to exert a closing tendency on the doors which is greatest when both doors are closed. A

In the accompanying drawing which illustrates my invention, 7 v

1 Figure 1 is a side view of the can complete,

Figure 2 is an enlarged vertical sect on through the upper portion of the can 1ncluding its cover,

Figure 3 is a bottom plan view of the cover removed, and

Figure 4 is a view similar to Figure 2, showing one of the doors in open pos t on.

Referring now to these figures my invention is utilized in connection with a vertlcal cylindrical can body 10 having a closed base and an upper open end'provlded until a reinforcedsurrounding edge 11, telescopingly engaged by the lower offset flange- 12\of the open end of a substantially semi-globular cover 13.

The cover 13 has at diametrlcally oppos te points openings 14 through which material may be introduced within the can while the cover is in closed position, these openings being normally closed by a pair of inward swinging doors 15-withinthe cover, hinged Each door 15 has inner brackets 18 to I The links 19 with their pivotal connections to the doors and to eachother form atoggle in which the links 19 serve as strut links. 4 The parts are so proportioned and arranged,

that when both doors areclosed the toggle does not completely straighten and in'all positions which the doors may assume the weight of the enlargements 21 urges both,

doors toward their'closed positions/ Thus either door may be-pushed open regardless of the position of the'other door and, when released, will be automatically closed.

It should be observed that the pivots at theends of the links 19 approach alinement as the doors close. Consequently, the'closing thrust exerted on the doors by the weight of. the enlargements 21 is greatest when both doors are closed. This is a valuable charac= teristic for it insures maintenance of the doors in closed position, while allowing the doors to open with increasing ease as the opening movement progresses. This characteristic has special utility in structures such as that shown in the drawing, in which the an opening tendency due to its own weight. Thus it is obvious that while effectively operating to maintain both doors in closed door is sopositioned when closed as to have I pose of introducing material within the can,

the door or doors so opened automatically closing when released so that the can will be maintained in fireproof relation inso far as the communication of fire either to or from 'its'contents is concerned.

I claim: Y 1. A fireproof waste can including a body,

l a removable cover for the body having opward closed position independently positely disposed door openings, doors hinged to and swingable within the cover and seatable against the inner face of the cover around said openings, and vertically yieldable connections between the doors, free of contact with the cover and acting by gravity to normally hold the doors in their oute closed positions.

2. A' fireproof waste can including'a body,

a removable cover having oppositely dis posed side door openings doors swingable within the cover-to seat. against its inner face around said openings, and gravity controlled pivotal connections vertically yieldable between the doors and free of contact with the cover, for holding the doors by gravity in outer closed positions.

3. The combination of areceptacle having an opening; an inward opening door hinged to said receptacle andserving to close said opening; and a gravitating toggle linkage mounted within said receptacle, connected with said door, and serving to urge said door closed with a thrust which increases as the door approaches closed position.

4. The combination of a receptacle having a pair of openings inward opening doors hinged to said receptacle andserving to close said openings; and. a gravitating toggle link.- age mounted within said receptacle, connected with said doors and urging each door toof the position of the other door. r

5. The combination of a receptacle having a pair of openings; inward opening doors hinged to said receptacle and serving to close said openings, said doors having an opening tendency due to their own' We ght when closed; and a gravitating toggle linkage fmounted within said receptacle, connected inane i2 with said doors and serving to urge each doorolosed regardless of the position of the other door, said linkage being constructed and arranged to exert its greatest thrust against said doors when both doors are closed. 6. The combination of a receptacle having opposed openings; inward opening doors hinged to said receptacle and serving to close said openings; a pairof links hinged to said doors and to each other; and means for urging said links toward 'alinement with each other, whereby 'aclosing tendency is exerted upon the doors.

7. The combination of a receptacle having a "plurality of openings; a plurality of inward opening hinged doors arranged to close said openings; a weight; and a plurality of links connected with said weight and each linkconnected with. a corresponding door, the weight and links being so arranged that the weight constantly exerts a-closing ten',

dency on all the doors, in all positionsthere- The combination ofa receptacle having a pair of openings, inward opening doors hinged at their upper ends to said-receptacle and serving to close said openings,

ROBERT BLANK.
